| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o ATA is now fully newbus'd and split into modules. This means that on a modern system you just load "atapci and ata" to get the base support, and then one or more of the device subdrivers "atadisk atapicd atapifd atapist ataraid". All can be loaded/unloaded anytime, but for obvious reasons you dont want to unload atadisk when you have mounted filesystems. o The device identify part of the probe has been rewritten to fix the problems with odd devices the old had, and to try to remove so of the long delays some HW could provoke. Also probing is done without the need for interrupts, making earlier probing possible. o SATA devices can be hot inserted/removed and devices will be created/ removed in /dev accordingly. NOTE: only supported on controllers that has this feature: Promise and Silicon Image for now. On other controllers the usual atacontrol detach/attach dance is still needed. o Support for "atomic" composite ATA requests used for RAID. o ATA RAID support has been rewritten and and now supports these metadata formats: "Adaptec HostRAID" "Highpoint V2 RocketRAID" "Highpoint V3 RocketRAID" "Intel MatrixRAID" "Integrated Technology Express" "LSILogic V2 MegaRAID" "LSILogic V3 MegaRAID" "Promise FastTrak" "Silicon Image Medley" "FreeBSD PseudoRAID" o Update the ioctl API to match new RAID levels etc. o Update atacontrol to know about the new RAID levels etc NOTE: you need to recompile atacontrol with the new sys/ata.h, make world will take care of that. NOTE2: that rebuild is done differently from the old system as the rebuild is now done piggybacked on read requests to the array, so atacontrol simply starts a background "dd" to rebuild the array. o The reinit code has been worked over to be much more robust. o The timeout code has been overhauled for races. o Support of new chipsets. o Lots of fixes for bugs found while doing the modulerization and reviewing the old code. Missing or changed features from current ATA: o atapi-cd no longer has support for ATAPI changers. Todays its much cheaper and alot faster to copy those CD images to disk and serve them from there. Besides they dont seem to be made anymore, maybe for that exact reason. o ATA RAID can only read metadata from all the above metadata formats, not write all of them (Promise and Highpoint V2 so far). This means that arrays can be picked up from the BIOS, but they cannot be created from FreeBSD. There is more to it than just the missing write metadata support, those formats are not unique to a given controller like Promise and Highpoint formats, instead they exist for several types, and even worse, some controllers can have different formats and its impossible to tell which one. The outcome is that we cannot reliably create the metadata of those formats and be sure the controller BIOS will understand it. However write support is needed to update/fail/rebuild the arrays properly so it sits fairly high on the TODO list. o So far atapicam is not supported with these changes. When/if this will change is up to the maintainer of atapi-cam so go there for questions. HW donated by: Webveveriet AS HW donated by: Frode Nordahl HW donated by: Yahoo!

* Change the disk(9) API in order to make device removal more robust.phk2004-02-181-20/+23
| | | | | | | | | | | | | | | | | | | | | | | | Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly.

* Use UMA instead of plain malloc for getting ATA request storage.sos2004-01-141-0/+1
| | | | | | | This gives +10% performance on simple tests, so definitly worth it. A few percent more could be had by not using M_ZERO'd alloc's, but we then need to clear fields all over the place to be safe, and that was deemed not worth the trouble (and it makes life dangerous).
* Overhaul of the timeout/reinit framework. This should clear up mostsos2004-01-111-4/+5
| | | | | | | | | | | | of the leftovers from the old version that really doesn't work anymore. Add a reset function for host-end of the ATA channel. This is needed for the SiI3112 in order to whack it back to reality if a device locks up the SATA interface (thereby preventing that we can reset the device). The result is that ATA now recovers from the timeouts that happens with the SiI3112A and more or less all disks based on old PATA electronics with a Marvell PATA->SATA converter. This includes lots of the popular SATA dongles and the WDC Raptor disks..

* This is a major rework of the ATA driver (ATAng)sos2003-08-241-28/+40
| | | | | | | | | | | | | | | | | | | | | | Restructure the way ATA/ATAPI commands are processed, use a common ata_request structure for both. This centralises the way requests are handled so locking is much easier to handle. The driver is now layered much more cleanly to seperate the lowlevel HW access so it can be tailored to specific controllers without touching the upper layers. This is needed to support some of the newer semi-intelligent ATA controllers showing up. The top level drivers (disk, ATAPI devices) are more or less still the same with just corrections to use the new interface. Pull ATA out from under Gaint now that locking can be done in a sane way. Add support for a the National Geode SC1100. Thanks to Soekris engineering for sponsoring a Soekris 4801 to make this support. Fixed alot of small bugs in the chipset code for various chips now we are around in that corner anyways.

* First round off updates/fixes to the ATA driver.sos2003-02-201-13/+17
| | | | | | | | | | | | This moves all chipset specific code to a new file 'ata-chipset.c'. Extensive use of tables and pointers to avoid having the same switch on chipset type in several places, and to allow substituting various functions for different HW arch needs. Added PIO mode setup and all DMA modes. Support for all known SiS chipsets. Thanks to Christoph Kukulies for sponsoring a nice ASUS P4S8X SiS648 based board for this work! Tested on: i386, PC98, alpha and sparc64

| | | | | | | | | | | | | doesn't give them enough stack to do much before blowing away the pcb. This adds MI and MD code to allow the allocation of an alternate kstack who's size can be speficied when calling kthread_create. Passing the value 0 prevents the alternate kstack from being created. Note that the ia64 MD code is missing for now, and PowerPC was only partially written due to the pmap.c being incomplete there. Though this patch does not modify anything to make use of the alternate kstack, acpi and usb are good candidates. Reviewed by: jake, peter, jhb

Inside struct disk we had a struct disklabel which disk drivers used to communicate certain metrics to the disklayer above (GEOM or the disk mini-layer). This commit changes this communication to use four explicit fields instead. Amongst the benefits is that the fields do not get overwritten by wrong or bogus on-disk disklabels. Once that is clear, <sys/disk.h> which is included in the drivers no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in, the few places that needs them, have gotten explicit #includes for them. The disklabel inside struct disk is now only for internal use in the disk mini-layer, so instead of embedding it, we malloc it as we need it. This concludes (modulus any mistakes) the series of disklabel related commits. I belive it all amounts to a NOP for all the rest of you :-) Sponsored by: DARPA & NAI Labs.
